devzat: Server doesn't accept RSA SHA-2 keys.

I’m getting a permission denied error even though I have a public key generated. Any ideas?

λ ssh pixelmonk@devzat.hackclub.com
pixelmonk@devzat.hackclub.com: Permission denied (publickey).

λ ls ~/.ssh
id_rsa  id_rsa.pub  known_hosts  known_hosts.old
